It is but you said you couldn’t afford the payment so wanted to lease then buy it out. How long do you plan on keeping the thing? Anyway look at it like this, I’ll use the following deal as an example why you shouldn’t buy it.
$273 * 35= $9555 $9555+675=$10230 total payments
residual $30034 * 1.10 tax rate=$33037+$10230= buyout + total payments=$43267
So leasing one of these then buying it out will cost $43267 and that doesn’t even include interest on the buyout of $33307. So take that $43267/$273=153 months or about 4.4 36 month leases. Explain to me why you want to buy one of these, of course things won’t stay the same price over the next 153 months but I would assume you could lease at least 3 trucks over 9 years for the $43k or buy one and in 10 years you’ll have a 10 year old truck that is clapped out. Oh and I forgot to add this, leasing three trucks over 9 years would cost $29484, assuming the $273/mo, not likely.
